We also add the 4 Gigabit MAC Device Tree nodes within the brcm,bus-axi

Commit 1b47b98a ("ARM: BCM5301X: Add DT entry for SPI controller and

However there are also devices with two flash memories:
1) Small SPI attached flash used mostly for booting
2) Bigger NAND used mostly for storing firmware
On such devices we still need SPI-NOR e.g. to access NVRAM data.

The memory range assigned to the PMC (Power Management Controller) was
not including the PMC_PCR register which are used to control peripheral
clocks.

This was working fine thanks to the page granularity of ioremap(), but
started to fail when we switched to syscon/regmap, because regmap is
making sure that all accesses are falling into the reserved range.

An error in documentation of the NAND Flash Controller (NFC) led to choose
another compatibility string for sama5d2 with an impact on the NAND flash
ready/busy information. It was producing the error message:

atmel_nand 80000000.nand: Time out to wait for interrupt: 0x08000000

and had an impact on performance.

So, switch back to the classical "atmel,sama5d3-nfc" compatibility string for
this SoC which gives the proper ready/busy bit information. The NAND flash
driver will be updated to remove the support for this different
implementation.

Configure the two accelerometers sharing GPIO line 82 as:

- Open drain so that they can share the same interrupt line.

Configure the corresponding interrupt pin:

- Trigger on the falling edge since open drain implies that we
  do not actively drive the line high, but we will actively drive
  it low to generate interrupts and then it moves from high to low
  i.e. a falling edge.

- Pulled up so the line will be biased to high unless an IRQ
  is active on any device on the line, and thus it goes high
  again after the interrupt is deasserted.
